GÉANT Developments

What is GÉANT ?
  • Pan-European Network connecting 28 NRENs from
    across Europe
  • Based on 10Gbps capacity, using Juniper routers
  • Global Research connectivity
  • US, Canada, Japan
  • Platform for development and deployment of
    advanced services (QoS, IPv6, MPLS)
  • Jointly funded by NRENs and EC

3
Multi-Gigabit pan-European Research
Network Backbone Topology December 2002
  • Connecting 32
  • European Countries
  • and 28 NRENs
  • Backbone capacity in
  • the range of
  • 34Mb/s-10Gb/s

4
Backbone Access Speeds - August 2002
5
Global Research Connectivity
  • 3 x 2.5Gbps connectivity between Europe (AT, DE,
    UK) and US (NYC, DC)
  • Interconnections with Abilene, CAnet4, ESNET,
    SINET
  • NSF funded initiative to provide 2 x 2.5Gbps
    between Chicago and Amsterdam
  • 155Mbps connection London-Tokyo

Other Regions
  • ALICE (South America)
  • EUMEDCONNECT (Mediterranean)

The ALICE Project
  • America Latina Interconectada Con Europa
  • The objective of ALICE is to create a regional
    Latin American research networking infrastructure
    and its interconnection to GEANT. The ALICE
    project is co-funded by the European Commission.

10
Possible Latin American network topology
  • Major connectivity between AR, BR, CL, MX (at
    least 45 Mbps)
  • Other countries connect to major nodes (between
    10 and 45 Mbps)
  • Connectivity to Europe at least 155 Mbps
  • Topology dependent on result of the ALICE tender
  • IPv6, QoS, Multicast

11
ALICE Timetable
  • ALICE contract to be signed early April 2003
  • Procurement Recommendation October 2003
  • Main backbone ring (Mexico-Chile-Argentina-Brazil)
    and connectivity to GEANT end 2003
  • Successive network roll-out to all other
    countries
  • EC funding will last until 31 March 2006
  • Sustainability after 2006 to be ensured by CLARA
    (Cooperacion Latino Americana de Redes Avanzadas)

12
EUMEDCONNECT
  • NRENs in Algeria, Cyprus, Egypt, Israel, Jordan,
    Lebanon, Malta, Morocco, Palestinian Authority,
    Syria, Tunisia, Turkey
  • Project Partners DANTE (UK), GARR (Italy), GRNET
    (Greece), RedIRIS (Spain), RENATER (France)
  • Project supported by EC EUMEDIS programme

14
How do we get there?
  • Topology to be agreed during tender negotiations
  • Initial topology could include
  • Direct MED-NREN connections to GÉANT
  • Satellite links
  • local hubs
  • Evolution to target topology as soon as
    achievable
  • Timescales Tender currently underway
  • Service from late 2003-2006

15
The Services
  • Best Efforts IP
  • Premium IP
  • LBE (scavenger)
  • Multicast
  • MPLS-based VPNs
  • IPv6
  • Interdomain Performance Monitoring

16
Premium IP
  • Separate IST project (SEQUIN) for the definition
    of Premium IP
  • Validated, deployed on GEANT
  • Based on diffserv-EF

17
Architecture
Classify (DSCP) High priority queueing on all
nodes
Do not police on egress Do not shape
18
Use of Premium IP
  • IST projects AQUILA, MOICANE, LONG
  • Request for and configuration is not yet
    automated
  • ongoing work
  • http//www.dante.net/nep/geantqos/premiumip.html

19
IPv6
  • GÉANT configured since February 2003 with dual
    stack operation
  • First NREN connections next week!
  • Abilene to follow in May 2003
  • All other NRENs connected by October 2003

20
L2 VPN
  • Provision of emulated switched point to point
    connections, using Juniper MPLS/CCC
  • 6NET STM-1 between Germany and Greece
  • ATRIUM STM-4 between Poland and France
  • DATATAG STM-4 between CERN and Italy

eVLBI
21
What next ?
  • GÉANT funding ends November 2004
  • FP6 call for successor network May-September 2003
  • Work for successor ( RfP, FP6 bid) starts now

22
The Technical Requirements
  • Support IP(v6) based services, perhaps at higher
    aggregate capacities (gt 10Gbps)
  • Switched point to point connections, from STM-4
    to 10GE
  • middleware for interdomain resource allocation,
    AAA ?
  • Support for GRIDs

23
Network Architecture options
  • Routed (IP only)
  • Mix of switched routed
  • SDH or GE or both ?
  • Connectivity (depends on costs and locations)
  • managed wavelength/SDH
  • DIY (see CH, CZ, PL, NL)
  • mix of both

24
Thank You
25
Largest GRID Application on GÉANT yet
  • VLBI - Very Long Baseline Interferometry
  • e-VLBI - Real-time VLBI done using network
    interconnectivity
  • EVN - European VLBI Network
  • 14 radio telescopes in Europe
  • plus others further afield
  • JIVE - Joint Institute for VLBI in Europe
  • hosts Mk IV correlator (dedicated supercomputer)
  • JIVE hosted by ASTRON at Dwingeloo in The
    Netherlands
  • See http//www.evlbi.org

Current arrangement uses tapes...
  • Tape technology nearing EOL
  • One supplier left
  • 1200 per tape
  • Drives no longer available
  • Expensive logistics
  • Effectively limits bit rates
  • Hence limits resolution
  • Slow turn around time
  • Real-time measurement not possible
  • Inflexible duty cycles
